This machine adopts synchronous control technique. The cent-control and welding time are composed of PLC program system . The input front-panel has two forms, touch screen and keyboard that makes the machine more intelligent and reasonable and it could press at one time, times welding . Welding by electromotor ; the hopper adopts the steeping motor; brake motor wheels ;pulling the wire net is controlled by the steeping motor . The line wire and the weft wire are pre-straight and pre-cut . The greatest advantage is you can adjust the distance of weft wire at random on the same one piece wire mesh sheet.
